SECIFICATION.

TO ALL WHOM IT MAY CONCERN: l p p p Be it known that I, JOHN F. SANFORD, of Keokuk, in the county of Lee, and State of Iowa, have invented an Improvement in Lamp-Burners; and I do hereby declare that the following isafull, cleaigand exact descrip` tion thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a view of one side of the burner. Figure 2 is a view of the upper movable section of theburner, showing a door on the side ofthe same. i Figures 3 and '4 are views showing the wicleadjusting spurs in two positions. Figure 5 is a top view of the burner with the cone removed. i v i Figure 6 is a section through the upper section of the burner, takenin the horizontal plane indicated `by red line :c a: in iig. 2. f i Figure y7 is a perspective view of the wick-spur bearing. Similar letters of reference indicate corresponding parte inthe several figures. i

This invention consists in providing for removing the wick-adjusting spurs from a lamp-,burner at pleasure, l for the purpose of sharpening them when their points become so dull as to :ict imperfeetly upon the wick Vsaid spurs being supported, when in the burner, upon bearings which are adjustable, and by means of` which `the ,i wick-spurs can be set nearer to theivick, as may be desired, for the purpose of keeping the spurs in good working order for a great length of time, as will be hereinafter described.

The invention also consists in applying a pivoted valve or doorto the outside of the burner-case foreoveringan opening whiclfiis Inade through said case for the purpose of receiving through it a lighted taper for lighting 1 the wick without removing the chimney; said valve being acted upon by a spring for holding it implaceovcr its opening, and so arranged `as to be operated or closed by an upward and downward` or vertical pressure, `as will be hereinafter described. 'lo enable others skilled i'n the art to understand my invention, I will describe its construction and operation. Externally, the lamp-burner may bcrmade of the same shapes as theivell-known burners `which have` been" in eomxiion use before my invention. The body of the burner consists of two sections, and B," which are hori-A yzontully divided, and connected together by a pin and thumb-screw, as shown in the drawings,iiigs.3 andi, or i in any other suitable manner, which will admit of the removal of the perforated section B from `the,tube-holding sectionA at pleasure. The upper section, B, is provided with a thumb-screw, a, for holding the chimney in place, also with a cone, C, as shown in figs. 1, 3, and 4. The wick-tube b is secured to the bottom of` thelowelf section, A, and to the lower -part of this wiclbtube a thin metal plate, c, is suitably secured, which ,projects 'upward nearly to the top of the burner, and on that side thereof which is opposite the `adjusting-spurs forrnising i and lowering the wick. This plate, c, is constructed with two bearings, el fori the stern, d, of the wick-spurs,

e. The bearing, c, is perforated for receiving the inner end of the stem "d, and thefhearing c ispniade in the form of a hook, asshown in iigs. 5 and 7, for the purpose of allowing of the removal `of the stem d with itsspurs i when the upper section B is-detachcd from the lower section. There is an oblong notch made in the upper edge of the lower section, A, coinciding with the openings through the bearings cheifor the purpose of receiving through it the stem d so that one end of this stern will project outside of the burner, as Ashown in figs. 1 and 5;. A thumb-screw, c, is tapped through the upper end of the plate c and bears against the wick-tube, as shown in figs. 3 and 4. By means of this screw the axis of the stem d can be adjusted nearer to or set further from thc i wick-tube, as may be required.` The plate c may be made of spring metal'and sonpplied t-o the wick-tube that the upper end of this plate will press against the upper end of the wicktube when it is not resisted andheld out by the screw el. This will keep the stem d steady/ and canse the spurs'e e to beheld 'firmly in contact with i the wick. An opening is made through the side ofthe 'wick-tube in the usual manner, for allowing the spurs ee i to iinpinge upon the wick and to move the latter `when the stem d is turned. It has been found thatthe points` of ther spurs e e will in a very short time become so dull that they will cease to operate perfectly upon the wicks in the tubes. When this occurs the section B is removed and the spurs e e taken out and sharpened. When these spurs are returned to their place in the burner they are adjusted up to the wick by the set-serew e, so as to compensate for the difference in diameter of the spurs after they are sharpened, by bringing the'irjaires nearer1 to the wick. In this way the spurs c e can be kept sharp and in good working ordern-s long asthebodyof the burner serves its purpose.

Hitherto the Wick-adjusting spurs have been applied permanently to the burners, and could not be convenently removed, for whiehre'ason the burners are thrown aside as useless when the spurs cease to operate well. ,1

An opening, i, is made through the upper section, B, for the purpose of receiving through -it a lighted taper lor lighting the wick without' removing the chimney. This opening is closed, when the lamp is lighted, by means. if a perforated valve, g, the extension of which is pivoted to the burner section vas shown in figs. 2 and 6, so is to be opened and closed by a vertical pressure. A lip, z', is struck up from the section A so as to impingc ipon the edge of the valve g, when this valve is closed, and keep itin place.

I am aware that it is not new to have lighting" holes through the burners of the lamps, nor is it new to :lose such holes by means of laterally movable slides, and therefore I do not claim such an arrangement asny.' nvention'. It will be seen that the valvefg is so applied te the burner that there will be no danger, from upset- :ing a lamp, in opening and closing it, asthe pressure is applied in a vertical instead of alatcral or horizontal `n'essure. i Y t i What I claim as new, and desire to secure by Letters Patent, is Theapplication of a wick-'spur stem, d, to adjustable bearings in such manner that this stem, with its spurs, :an be removed from the burner at pleasure, substantially as described.

2. Constructing the body of the burner of two sections, A B, in combination with wick-spurs, which are sol tpplied that they can be detached from their bearings, el c2, at pleasure, substantially as described.

Witness my hand, the matter of my application fopa patent for improvement in lamp-burners. 1
